(K.U.T) Keychain Utility Tool by LarkysPrints on Thingiverse: https://www.thingiverse.com/thing:2843853

Summary:
This is an easy to print one piece utility blade holder with a 6 cm ruler. The tool could be used for light cutting tasks and could be clipped to a keychain for everyday carry. There are 2 versions for this design. One has a solid body for added rigidity and the other has a finger groove for easier deployment. Both versions also have an alternate file where the lockbar is extended further to accomodate larger stanley blades as the general dimensions of each brand of blade may vary slightly.WARNING: It is not advised to apply too much force on the tool when cutting larger or tougher items as the tool may fail under large pressure. This tool is designed for light cutting tasks only.
